Thor joins his fellow Avengers for Avenger Day, a celebration held in Central Park honoring the Avengers for their recent victory against the Mandarin. Thor attends reluctantly, grumbling, “Must the mighty Avengers be reduced to mere clowns– strutting and fretting for the benefit of mortals?” He makes an early departure, before the team can surprise Hercules by formally inviting him to join the team. (They had wanted to invite Black Widow as well, but she has decided to retire from superheroics.)
There is a footnote in this issue indicating that it take place before the events of Thor #145. That means that it and last month’s annual must take place shortly before the events of Thor #143.
